With the release of the Adobe Creative Suite 4, all the major apps have adopted a tabbed document interface. At first it’s a bit difficult to get used to, but I’ve found it to be a pretty decent productivity increase. The one thing that baffled me was how difficult it was to get objects from one document to another. I of course am not one for reading manuals, so it took me a while to figure out how simple it really is. You can drag objects (or entire layers for that matter) from one document to another when they’re both open simply by selecting the object(s) or layer(s) from one document and dragging them to the tab of the second document and hovering them over the tab for a brief second. The second document moves to the front and you can let go of them to place them.
